Pumps' Perplexities

It is being said that the hydrogen car is the car of the future.....
Clean, safe and reliable.....For some reason I doubt this....
For years, the technology has existed to convert any standard
gasoline engine to use with propane.....It is a simple
carburetor conversion kit designed in the mid-70s......

While some "on the road" vehicles do use propane, most
propane is used in fork lift trucks operated in a large
indoor warehouses......Propane does not pollute if it burns
cleanly.....

To use propane in an "on the road" vehicle you must properly
protect the "propane tank" which is in the rear of the
vehicle......A rear end collision involving a propane powered
vehicle can cause a problem if the "tank" or its fuel line is
ruptured.....One unnecessary spark and --........

Hydrogen is more volatile than propane.....You will have
to design the vehicle with a "tank" to carry it as a the fuel
source.....Perhaps the model name of this vehicle should be
called the "Hindenburg"......Pumps
